NPR’s Robert Krulwich (one of the greatest science journalists ever IMO, and a personal hero of mine) writes about the day he received an email from the late astronaut Neil Armstrong. Krulwich wondered, “How come they walked such a modest distance? Less than a hundred yards from their lander?” And Armstrong basically answered that they were “part of a team and we were team players on a perilous, one-of-a-kind journey. Improvisation was not really an option.” But Krulwich adds, “I kinda think he wanted to do more, go further. Anyway, read for yourself.” (via Steve Silberman)
